# Sovryn Onboard

Sovryn-onboard is a wallet connection library that when integrated into a dapp, allows users to connect their Web3 wallets to sign messages and transactions. It's modular so each part can be easily changed, with a split between core and connector packages.

Modules are forked from and therefore compatible with [web3-onboard](https://github.com/blocknative/web3-onboard). Most changes are to add additional features required by Sovryn.

Core packages are required for library to work seamlessly and connectors are optional.
